You might search for an official service manual on your exact year model, they can change the valve clearances as they go and sometimes because cams got changed in some way for durability reasons commonly. The exhaust is the one that will bite, the fact the clearances are closing up says valves are probably receding and doing it on exhaust will burn the valves. Why the compression came back up. I'd run the bike a little hard for a bit to beat through any carbon that built up on the exhausts, sometimes you do and then suddenly you need to set the valves again when they beat through carbon and got closer again. I drove a certain bike that you might have to set the valves twice before they settled in to stay after the carbon was gone.
